Help with upgrading current pc

Posted by Huge_Elk_7434@reddit | buildapc | View on Reddit | 8 comments

I have got a pc that shuts down and turns on again when I play games that are a tiny bit demanding. I can only play games like Roblox, Minecraft (lags a lot tho) and sims 4 but when I try to play other games. It shuts down. I got house flipper and it was going great then a couple days ago it shut down for the first time and today it done it twice! I want to play high demanding games like red dead redemption and Forza horizon 5

My pc specs-

CPU: AMD Ryzen 3 3200G with Radeon vega graphics (4 CPUs)

GPU: NVIDIA GeForce GTX 1070 Ti

RAM: 16 GB

Storage: 932GB HDD

Power Supply: Fierce PC ATX, 450W, silent 120mm fan

I’m not that knowledgeable on pcs so idk what I should replace etc. also this will be my first time upgrading/building my pc so any tips so I don’t mess anything up would be great! If you think that I would just be better to buy a new pc then let me know as well!
